[Feature] Style authors are now able to define the default submit button used for form submission on ENTER keypress on forms using more than one submit button. Prosilver uses this for the posting page(s) and registration screen.

[Feature] Ability to specify amount of time user is able to delete his last post in topic.

[Feature] Added the possibility to force user posts put in queue if post count is lower than an admin defined value. Guest posting is not affected by this setting.

[Feature] Added 'max_recipients' setting for private messages. This setting allows admins to define the maximum number of recipients per private message with a board-wide setting and a group-specific setting.

[Feature] Added new permission setting for sending private messages to groups. Now there are two permissions to define sending private messages to multiple recipients and private messages to groups.

[Feature] Allow specific connection to different server for jabber functionality by providing a valid JID as username. This also allows the use of talk.google.com as jabber server with gmail.com JIDs. (Bug #14989)

[Change] For new posts or editing the first post topic titles have a maxlength of 60 characters. For any subsequent posts the length is extended to 64 to make room for the Re: part, but cutting at 60 characters. The maxlength need to be 64, else users using opera are unable to post (opera does not allow pre-filling a field with more characters than specified within the maxlength attribute)

[Fix] Disable gzip compression for cached stylesheet for Internet Explorer 6 or empty browser (IE6 is not able to properly display the compressed stylesheet) (Bug #14054)

[Feature] Allow "older" updates applied with the automatic updater. This allows people using it for updating, say, from 3.0.0 to 3.0.1 (with the correct package of course) and then from 3.0.1 to 3.0.2 if the latest version at this time is 3.0.2. These changes take effect beginning with RC4 or people replacing install/install_update.php manually prior doing the updates.

[Change] Re-implemented All Yes/No/Never links in permission panels for easier changing all categories at once

[Change] Advanced permission link now "marked" if no role is assigned and custom permissions set. With this an admin can instantly see if the object is not set at all or having custom permissions, something you only saw if advanced permissions were viewed before.

[Feature] Allow dropping in custom "info_[module class]_*.php" files to language/*/mods directory for inclusion into the menu structure without the need to modify phpBB language files for menu placements
